    摘要: A breathing assistance system includes a gas delivery system that generates a gas flow, a fluid source (e.g., a humidifier system or supplemental gas supply) located downstream from the gas delivery system that humidifies the gas flow generated by the gas delivery system, a gas flow conduit system for communicating the gas flow from the gas delivery system, and a flow regulation device. The flow regulation device is physically moveable between (a) an operational position that allows the gas flow generated by the gas delivery system to flow downstream past the flow regulation device via the gas flow conduit system, and (b) a protection position that prevents gasses and liquids flowing upstream through the gas flow conduit system from reaching the gas delivery system, and instead directs such gasses and liquids through an exhaust opening in the gas flow conduit system. The flow regulation device automatically moves between the operational position and the protection position based at least on a gas pressure upstream of the flow regulation device.
